I don’t think the devs are going to remove a livery. You can vote for the A332 here though:
Unfortunately, there are no plans to add the A330-300, because we do not currently have the correct engines modeled. Unless the A330 gets a full rework, we most likely won’t be getting the Aer Lingus livery on the A333.
Infinite Flight won’t remove liveries, Aer Lingus ordered A350’s but transferred them to Iberia. They are still kept in game though, and the majority of us want it to stay. A link has been provided above which you can vote for if you want to keep realism at most.
Also a simple ‘copy and paste’ onto the A330 ‘frame’ is nowhere near how it works 🙃
I don’t know why this discussion has continued to this extent. The two links for the feasible part of the request are below, this is your part to get this request up and running.
There currently is not an active A330-300 request thread.
Yes, I know that the copy and paste is not relevant and not how it works. I know there are man hours that go into the design of of every livery and the extent of it. Funny how we all strive to make the game more realistic, but when the actual concept of doing so arises, it’s shot down with the naysayers. Why do things realistically when we have virtual airlines which typically aim to keep it real.
